Thanks for figuring out the problem and documenting a fix. I really
appreciate documentation patches.

I wonder about the details of this particular fix. Usually, when there
is a configuration file in a .d directory, like depmod.d, it is possible
to add more files to the same directory that also get used for
configuration. When that works, it is usually better to add files to
the directory rather than changing existing files, because it behaves
better on upgrade. So, in this case, I wonder whether it is possible to
add a new file that would have something like:
search extra
or
override kmod * extra
The latter is suggested by depmod.d(5).
